Consider the functions below. f(x) = X g(x) = 9 X-4 X (a) Compute (fo g)(x). Be careful when you input compound fractions. 92 (fog)(x) = x 92 X x (b) Determine the domain of fo g. O all real numbers except 0 and 4 O all real numbers O all real numbers except 9/4 O all real numbers except 0 and 9/4 (c) Compute (go f)(x). Be careful when you input compound fractions. (go f)(x) = (d) Determine the domain of fog. O all real numbers O all real numbers except 0 and 9 O all real numbers except 0 O all real numbers except 0 and 4
